Be it'linovrn. that We, linear il STEELE, WILMAM l'rnneon, :ind inno J. lnoirr, citizens of the United Stelzen ond rei'dentc of Jacksonville, in. the county oi Duvel ond @tete oi. Floride, have invented :i new ond improved Molding-Machine, of Wh ich the iollowing is n i'uli, cleer, end exact description.

'Uur' invention relates; to improvements in machines and molds for incl-ling plastic me tereis; i l

`While the principle ol' the invention ie cepeloie of general une for molding,` articles of various; kinds', it ie especially designed for brick-end ortiiicieletonc making and vviil he described with especial reference thereto.

Thelprincipel objects of the invention nre to provide ineens 'for smoothing the sides oi the molded articles as they are removed from n the mold, to provide for quickly ond eli cientlv'removingr them frointhc molde, to pro- Vide for attaching two articles together by nienneof en .insert placed in. there in the not of molding, to provide for o, convenient end eliicient introduction of the molding materiel into the molds, end to provide for adjustments to accommodate one seto'l' iii-olds to erticlce of different lengths.,

Further objects oi" the invention wiii nnpeerfinfthc course oi the suhjoincil descripu tion.

These Slots nre provided for the purpose of supporting' inserte i5, und the in- Sorts nrc designed for securing two bricks or hloclia. together, so es to provide for n, construction oi' double Well with en eirspece between the two perte without the necessity of nioiding; hollow blocks. lilrhen ordinary hloclre or liriche are to he mode, the slotted nietes i3 ere not need. The front ends of the molde nrc prefernhlv 'formed by e hinged plate lo, connected with the freine 10 :ind designed te receive the ende of the nietes 12 end 13 sind to desume :i vertical position in order to clone the ends of oil the molde when the molding;J operation ie 'being performed. in order to hold the front plete in that position, it is nrevided with` projections i7, end catches iii :ire mounted upon the outside weils of the mold. The reni ends oi the molds ere formed by pintee 19. These plates are provided with renrwerdif/extending projections 20, heving' elongeted siete QLthx-ongh each ot whichV passen e, thnnibnecrew 22 or other convenient fastening device. These thLimh-SCreiVs ere located upon movnhle oer 23, and consequentlgir they ere cepebie of holding; the nietes iii in. :itetionorv poeition, .hut provide for any ilceircd adjustment in order to inerente or decreeec the length of the article to he formed in the incid lUonneoted with the divisiompietes'; 12 und 13 isn freine tiri. This freine is provided with Screw--three .lcd hearings' 225 for receiving e rotctehie rod 26, having scrciv-threede- This rod ie mounted in hearings 27 on the frame end. ie provided with e crnnlf 11h' 'for operati ne; it. rl`hc rotntion ol this rod consce the recii mention ot the freine iol, nnd conseqiiei'itly of the divisiomplntee l2 :ind i3.

in order tosunpiy molding motorini to the molds :ind direct it to them in ii uniform ninnner, e movable hopper 25B is provided. 'This hns divieionqxletce 30, corresponr-lingn with the divsionmhites 12am] 13, endis provided with adjustable ende 3l, These endo :tre connected with o. ber32, which is edjustzihle ldingitudi-A neilyv in e slot 33 in a plete 34, connected with the sides of the hopper. A screw 35 on eeeh end of the bei' 32 ie need ior Securing the her in adjusted position in theslote 33. kN'lllisiiih justmcnt is provided in order tonnelle the hopper conform to the molds as they are adjusted. Connected with the rear of the hopper is a frame 36, which is pivotalljv connected with a lever 37, hinged or pivotedfat 38 to the rear part of the frame lO. A shelf 39 is preferably located upon the side ot the machine for receiving the product thereof.

The operation of the machine is very simple. rIhe plates 19 of the molds being adjusted to the desired position, the plate or pallet 11 is placed in front of and directly against the plates 19, the division-plates l2 and 13 are pushed forward to their extreme front position bythe operation of the crank 28, and the front plate 16 fixed in vertical position. The plates 31 of the hoppers are then adjusted so as to make the hoppers of the same length of the molds and the lever 37 operated to bring the hoppers directly above the molds, the hoppers being guided on top of the side plates of the molds by means of ways 40. The molding material is then introduced into the molds through the hopper and tamped, as usual. When the tamping operation is completed, the hopper is drawn back by the operation of the lever 37 and the rear side of the hopper will scrape oli the top of the molds and leave that face of the molded article in a smooth condition. j The catches 18 are then raised to allow the front plate to drop, and then the crank 28 is operated to pull the division-plates back. The plates 19 then act as strippers for the plates 12 and 13, and the molded articles are left on the bottom plate 11, which is designed to be lifted out and carried away with the moldedv articles upon it to the curingracks. ln case the inserts are desired to be included they will of course be inserted in tllie slots 14 before the molding material is app 1er 'While we have illustrated one form in which our invention may be embodied, it will be readily understood that the invention is not limited to this `loi-rn and can be carried out in many other forms and also that it is not limited to any particular molding material or to the molding ot' any 'particular objects.
